Chrysanthemum plant named &#39;MIORA ORANGE&#39;

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Miora Orange’, characterized by its upright, outwardly spreading and uniformly rounded plant habit; vigorous growth habit; freely branching habit; dense and full plant habit; dark green-colored leaves; uniform and freely flowering habit; and relatively large decorative-type inflorescences with ray florets that are initially red in color becoming dark orange and yellow orange in color with subsequent development giving the inflorescences a bi-colored appearance.

BOTANICAL DESIGNATION

Chrysanthemum×morifolium

CULTIVAR DENOMINATION

‘MIORA ORANGE’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Miora Orange’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Oostnieuwkerke, Belgium in October, 2009 of Chrysanthemum×morifolium ‘Caprioli Orange’, not patented, as the female, or seed, parent with Chrysanthemum×morifolium ‘Kismo Orange’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September, 2010.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2011. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Miora Orange’. These characteristics in combination distinguish ‘Miora Orange’ as a new and distinct Chrysanthemum plant:

1. Upright, outwardly spreading and uniformly rounded plant habit; vigorous growth habit.

2. Freely branching habit; dense and full plant habit.

3. Dark green-colored leaves.

4. Uniform and freely flowering habit.

5. Relatively large decorative-type inflorescences with ray florets that are initially red in color becoming dark orange and yellow orange in color with subsequent development giving the inflorescences a bi-colored appearance.

Plants of the new Chrysanthemum differ from the female parent, ‘Caprioli Orange’, in the following characteristics:

1 Plants of the new Chrysanthemum are smaller than plants of ‘Caprioli Orange’.

2. Plants of the new Chrysanthemum and ‘Caprioli Orange’ differ in ray floret color as inflorescences of plants of ‘Caprioli Orange’ have dark orange-colored ray florets.

Plants of the new Chrysanthemum differ from the male parent, ‘Kismo Orange’, in the following characteristics:

1. Plants of the new Chrysanthemum are more compact than plants of ‘Kismo Orange’.

2. Plants of the new Chrysanthemum have broader leaves than plants of ‘Kismo Orange’.

3. Plants of the new Chrysanthemum have larger inflorescences than plants of ‘Kismo Orange’.

4. Plants of the new Chrysanthemum and ‘Kismo Orange’ differ in ray floret color as inflorescences of plants of ‘Kismo Orange’ have light orange to salmon orange-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Nerola Orange’, disclosed in U.S. Plant Pat. No. 23,274. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Nerola Orange’ in the following characteristics:

1. Plants of the new Chrysanthemum were more compact than plants of ‘Nerola Orange’.

2. Plants of the new Chrysanthemum and ‘Nerola Orange’ differed in overall plant shape plants of the new Chrysanthemum were flatter than and not as spherical as plants of ‘Nerola Orange’.

3. Leaves of plants of the new Chrysanthemum were broader and not as dark green in color as leaves of plants of ‘Nerola Orange’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Miora Orange’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the spring and summer and under cultural practices generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 18° C. to 21° C. and night temperatures ranged from 10° C. to 15° C. Plants were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
